Tivoli Storage Manager for Windows Administrator's Guide


Selecting the Appropriate Device Driver for Tivoli Storage Manager Devices

Selecting the appropriate device driver depends upon the type of device and the media management technique. Devices supported by TSM can use the TSM device driver, and other devices can use Windows device drivers. The way administrators set up the two competing device drivers determines which one acquires devices when TSM is started.

Determine if Devices Meet Requirements for Using Windows Device Drivers with Tivoli Storage Manager

Devices may be used with Windows device drivers or with the manufacturer's device drivers, but the devices must have the following capabilities:

A file listing devices and their attributes can be created:

  1. Click Start>Programs>Command Prompt on the Windows Start button. The Command Prompt dialog appears.
  2. Change directories to the directory in which the TSM Server Utilities been installed. For default installations, the path resembles the following:
    c:\program files\tivoli\tsm\utils
    
  3. To create the file, type in the following command:
    adsmdlst devlist.txt
    
  4. To view the file, type in the following command:
    notepad devlist.txt
    

Select from the following device driver setup procedures based upon the device environment.

Controlling All Devices With the TSM Device Driver

The TSM device driver supports many manual and automated library devices. At many sites, the TSM device driver may be all that is required.

The TSM device driver is installed with the TSM server, but the device driver is unusable until the default behavior of the Windows device driver is controlled. By default, the Windows device driver tries to acquire all devices when Windows is started. If this happens, the TSM device driver is unable to acquire devices. Administrators must ensure that the TSM device driver acquires the devices that it needs by starting the TSM device driver before starting any Windows device driver.

To Configure the TSM Device Driver to Acquire Devices before the Windows Device Driver

To start the TSM device driver before starting any Windows device driver:

In the TSM Server Utilities...

  1. Double click the Server Utilities IconTSM Server Utilities icon on the desktop. The TSM Server Utilities window opens.
  2. Click Service Information IconService Information in the Server Utilities tree in the left panel. The TSM Services tab appears in the right panel.
  3. Right click TSM Device Driver. A pop-up menu appears.
  4. Click Options... in the pop-up menu. The TSM Device Driver Options dialog appears.
  5. Click to check the Enable Optical Device Support check box. The startup type is set to Boot as a default.
  6. Click OK.

In the Windows Control Panel...

Windows NT

  1. Click Settings>Control Panel on the Windows Start button. The Control Panel dialog appears.
  2. Double click Devices. The Devices dialog appears.
  3. Click the Windows device driver to select it.
  4. Click the Startup... button. The Device dialog appears.
  5. Click Manual. This ensures that the Windows device driver does not start until administrators enter the Control Panel dialog and manually start the Windows device driver.
  6. Click OK.


Windows 2000 Administrators using TSM with Windows 2000 do not need to explicitly control the Windows device driver's acquisition of devices. When the TSM device driver is in boot mode, it automatically acquires all devices not specified in its Device Exclude List.

Controlling Some Devices With the TSM Device Driver and Others With Windows Device Drivers

Some devices are not supported by the TSM device driver, but they can still be used with TSM using the Windows device drivers. At sites where a mix of supported and unsupported devices are used, both the TSM and the Windows device drivers may be used together.

An example of this scenario is an environment where some data is backed up to an automated library device and some data is backed up to an Iomega Jaz drive. The automated library device requires the TSM device driver. However, the TSM device driver does not support Iomega Jaz drives so the Windows device driver is used to allow TSM to back up to the Iomega Jaz drive.

To Configure Some Devices to Use the TSM Device Drivers and Other Devices to Use the Windows Device Driver

In the TSM Server Utilities...

  1. Double click the Server Utilities IconTSM Server Utilities icon on the desktop. The TSM Server Utilities window opens.
  2. Click Service Information IconService Information in the TSM Server Utilities tree in the left panel. The TSM Services tab appears in the right panel.
  3. Right click TSM Device Driver. A pop-up menu appears.
  4. Click Options... in the pop-up menu. The TSM Device Driver Options dialog appears.
  5. Click to check the Enable Optical Device Support check box. The startup type is set to Boot as a default.
  6. Click Exclude the Following Devices at Startup. The Device Exclude List gets focused. Enter the names of the devices that administrators want the Windows device driver to control. Separate the names with semicolons. These devices are excluded from TSM control when the TSM device driver is automatically started.
    Note:See Obtaining Alias Names for Devices. Adding TSM device names to the Device Exclude List may require an additional server reboot to update the Device Information view.
  7. Click OK.

In the Windows Control Panel...

Windows NT

  1. Click Settings>Control Panel on the Windows Start button. The Control Panel dialog appears.
  2. Double click Devices. The Devices dialog appears.
  3. Click the Windows device driver to select it.
  4. Click the Startup... button. The Device dialog appears.
  5. Click Manual. This ensures that the Windows device driver does not start until administrators enter the Control Panel dialog and manually start the Windows device driver.
    Note:After the system starts, administrators must manually start the Windows device driver so that it can acquire the devices excluded by the TSM device driver.
  6. Click OK.

Windows 2000 Administrators using TSM with Windows 2000 do not need to explicitly control the Windows device driver's acquisition of devices. When the TSM device driver is in boot mode, it automatically acquires all devices not specified in its Device Exclude List.

Controlling the Same Device With the TSM Device Driver and the Windows Device Driver

In some environments, administrators will want to use the same devices with both the TSM device driver and the Windows device driver. For example, this occurs when devices are used to back up data with TSM and then the same devices are used at other times to back up data with a different backup utility. This scenario requires a reboot of the system to switch between applications. The device drivers can be set up to give administrators the choice of starting either device driver.

To Configure a Device to Use the TSM Device Driver with TSM and the Windows Device Driver with Other Applications

Activate the TSM Device Driver...

  1. Double click the Server Utilities IconTSM Server Utilities icon on the desktop. The TSM Server Utilities window opens.
